. SAW GAUGE AND SET.

Application led March 26, 1923. Serial No. 627,881.

To @ZZ whom t may concern:

Be it known that I, FRANK Non, a citizen of the United States, and aresident of Lilliwaup, Mason County, Washington, have invented certainnew and useful Improvements in Saw Gauge and Set, of which the followingis a specification.

This invention relates to new and useful improvements in tools forsetting and gauging the teeth of saws, and the object of the inventionis to provide a tool that embodies both of these novel features in aunit structure.

rIhe invention resides in the novel arrangement, construction andcombination of parts, as will be more fully described in the follow ingspecification, illustrated in the accompanying drawings, and finallypointed out in the appended claim.

In accomplishing the objects of the invention, I have provided theimproved details of construction, the preferred forms of which areillustrated in the accompanying drawing, wherein- Figure 1 is a sideelevation of the tool, showing it in position against a saw blade forsetting the teeth thereof, and showing in dotted lines the position ofthe saw with respect thereto for gauging the set of the teeth.

Figure 2 is a front elevation of the same.

Figure 3 is a perspective view of the tool.

Referring more in detail to the drawings-1 designates, as a whole, atool constructed in accordance with the present invention. It consists,preferably, of an anvil block formed from a single piece of metal, of asize and shape that it may be conveniently held in the hand, and has aflat front surface 2 terminating along its upper edge in an inwardlybeveled surface 3.

Integral with the body, and offset inwardly from the surface 2, is anupwardly extending portion 4 provided at its upper end with a transverseslot 5 wherein the inner end of a tooth setting hammer 6 is pivotallymounted by means of a pin 7. The hammer is of angular shape, with adownwardly extending portion 8 and a head 9,

through which a pin 1() is extended and 50 which is substantiallyvperpendicular with respect to thel beveled surface 3. Adjacent thepivoted end of the hammer, the mounting portion is provided with anupwardly beveled surface 11 which normally extends 55 above the endsurface of the part-4 and which, upon being pressed downwardly by thethumb, will cause the hammer to be lifted outwardly, as is shown indotted lines in Figure l, to move it out of the way of the saw blade.Threaded through the upwardly extended portion of the body is a bolt 14which may be locked at set positions by a lock nut`15. The bolt is soadjusted that its inner end will serve as a gauge for the setting of theteeth of the saw.

`In using the device for setting the teeth of a saw and for gaugingtheir set, the tool is held in the hand and applied-to the blade of asaw 13, as is shown in Figure 1, the thumb of the hand in which the toolis held is used to depress the beveled end of the hammersupport to liftthe hammer outwardly when the tool is applied. The tool is held so thatthe end of the tooth lies adjacent the beveled surface 8. The thumb isthen removed so that the hammer pinlO may engage with the tooth of thesaw, as is shown in Figure 1, and the outer end of the hammer pin isthen struck a sha-rp blow so that it will cause the tooth to be setinwardly against the beveled surface. After this has been done thehammer is lifted by` pressure of the thumb against the surface 11 andthe tool is shifted downwardly so that the set of the tooth may begauged with respect to the end of bolt 14. By using the gauge in thismanner, all the teeth in the saw may be given the same even set.. A

It is apparent that a tool of this character can be easily applied andis very simple in its use and will satisfactorily perform the purposeforrwhich it is intended.

I-Iaving thus described my invention, what I claim as new therein anddesire to secure by Letters Patent, is:

A tool of the class described, comprising all anvil block having a planesurface termihating in a beveled edge, and having an eX- tension offsetfrom the plaiied Surface, a hammer pivotally supported from the eX-teiision and comprising a Striking member adapted to (2o-ziet With thebeveled surface in Setting a saw tooth, and a gauge bolt threadedthrough the extension of the anvil Where-
